OPA1662AIDGKRQ1 from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUT_A	output	Output of channel A; the datasheet specifies a continuous short-circuit rating to VS/2 (ground in symmetrical dual-supply setups), one amplifier per package.
2	-IN A	input	Inverting input of channel A; input current on all pins except the supply pins is limited to ±10 mA, and input voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V.
3	+IN A	input	Noninverting input of channel A; input current on all pins except the supply pins is limited to ±10 mA, and input voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V.
4	V-	power_in	Negative (lowest) power supply; the supply voltage (V+) - (V-) is specified at 3 V (±1.5 V) minimum to 36 V (±18 V) maximum, with 40 V as the absolute maximum.
5	+IN B	input	Noninverting input of channel B; input current on all pins except the supply pins is limited to ±10 mA, and input voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V.
6	-IN B	input	Inverting input of channel B; input current on all pins except the supply pins is limited to ±10 mA, and input voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V.
7	OUT_B	output	Output of channel B; the datasheet specifies a continuous short-circuit rating to VS/2 (ground in symmetrical dual-supply setups), one amplifier per package.
8	V+	power_in	Positive (highest) power supply; the supply voltage (V+) - (V-) is specified at 3 V (±1.5 V) minimum to 36 V (±18 V) maximum, with 40 V as the absolute maximum.
